Chemical Structure
Description
As a certified reference material (CRM), 3-(4-Iodo-1H-pyrazol-1-yl)-1H-1,2,4-triazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 3-(4-Iodo-1H-pyrazol-1-yl)-1H-1,2,4-triazole (CAS 2092431-39-3), a certified reference material (molecular formula C5H4IN5, MW 261.02 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Iodo-1H-pyrazol-1-yl)-1H-1,2,4-triazole (C5H4IN5) is characterized by a nitrile group, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
